its not a clunk stall noise... the pedal is just non responsive for a second..

for instance: say im driving on the freeway and im in 5th gear at 65 mph. i let off the gas as a car in front of me starts to slow. i downshift to 4th (making rpms higher) and once i push back on the gas, it bogs and then jerks forward.. i dont understand... im going to try tightening all of my connections to see if there are any leaks...

its not an rpm factor. its all something with the motor choking on too much air

it means the motor isnt getting the amount of fuel it needs..


the air to fuel ratio (afr) has more air in it then fuel

although the car still runs, the less fuel in the motor means the hotter it will get and more power if its not toooooo lean.

more fuel- cooler, but the car could lose power...

make sense?
